Noise and Vibration Laboratory

Planning and implementation of noise and vibration testing

The Noise and Vibration Laboratory performs standard and specific tests to support product development.

Common test types

Vibration

  • Sinusoidal
  • Random
  • Shock and knocking

Standard testing

  • Machine noise and vibration for CE mark
  • Environmental noise and vibration (noise laws)

Specific product vibration and acoustic tests

  • Operational Modal Analysis
  • 6 degree of freedom vibration - Establishment of test specifications
  • Noise reduction in machines/products. Sound Quality: Binaural Measurements
  • Squeak & Rattle tests
  • Noise tests on specific banks: Lift towers

Equipment

  • LDS V830 electrodynamic vibrator with sliding table for horizontal vibration
  • Climatic chamber for electrodynamic vibrator
  • Multi Axial System Test (MAST), vibration table 6 degrees of freedom
  • Climatic chamber for vibrator
  • Noise and vibration measuring equipment (up to 24 channels)
  • Transport recorder (for vibrations)
  • Sound level meter, Sound intensity probes
  • Vibrometer (measuring vibrations in the human body)
  • Recording equipment and binaural playback (acoustic head)
  • 3D Intensity probe
  • Probe microphone for noise inside pipes and small enclosures
  • Artificial ear (speaker noise)
  • Acoustic Camera for Squeak & Rattle testing
  • Specific vibration and noise test benches
